  2. 11. Micro-galvanic effects and corrosion inhibition of copper-zinc alloys

    Author : Mattias Forslund; Jinshan Pan; Christofer Leygraf; Per Claesson; Jin Ying; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Copper; zinc; brass; octadecanethiol; IR Spectroscopy; AFM; atmospheric corrosion; aqueous corrosion; corrosion inhibition; Koppar; zink; mässing; oktadekantiol; IR-reflektions absorptionsspektroskopi; AFM; atmosfärisk korrosion; vattenaktig korrosion; korrosionsinhibering.; Chemical Engineering; Kemiteknik; Kemi; Chemistry;

    Abstract :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. READ MORE

  4. 12. Atmospheric corrosion of copper and copper-based alloys in architecture : from native surface oxides to fully developed patinas

    Author : Tingru Chang; Inger Odnevall Wallinder; Tomas Prošek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Copper and copper-based alloys are commonly used in both ancient and modern architecture. This requires an in-depth fundamental and applied understanding on their atmospheric corrosion behavior at different climatic, environmental and pollutant levels and how these parameters influence e.g. READ MORE

  5. 13. Corrosion of current cullector materials in the molten carbonate fuel cell

    Author : Baohua Zhu; KTH; []
    Keywords : molten carbonate fuel cell MCHC ; corrosion; current collecotr; contact corrosion reistance;

    Abstract : The corrosion of current collector materials in MoltenCarbonate Fuel Cells (MCFC) is investigated. The essential aimsof this investigation were to study the corrosion behaviour ofdifferent materials, in varying cathode and anode MCFCenvironments, and to study the contact corrosion resistancesbetween the MCFC current collector and electrodes.

  6. 14. Superheater corrosion in biomass and waste fired boilers : Characterisation, causes and prevention of chlorine-induced corrosion

    Author : Peter Viklund; Christofer Leygraf; John Nicholls; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature corrosion; waste; biomass; superheater tubes; steel; alkali; chlorine; sulphur;

    Abstract : Biomass and waste fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work high temperature corrosion of superheater alloys, and methods to mitigate the problem, have been investigated by laboratory studies and controlled field exposures in commercial boilers.

  7. 15. Atmospheric Corrosion of Historic Lead Organ Pipes

    Author : Annika Niklasson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atmospheric corrosion; conservation strategies; formiate; historical organs; organ pipe corrosion; lead; oak wood; formic acid; acetic acid; acetate;

    Abstract : The atmospheric corrosion of lead is investigated, with the aim to improve the understanding of the environmental degradation of historical organ pipes. Fieldwork is combined with laboratory investigations. The field studies included characterization of the organ environment and exposures of lead coupons. READ MORE
